2 Claims. (Cl.99-194) This invention embodies a method of preservill by way of suitable control valves and flexible ing drawn and dressed fowl by refrigeration for pipes l8 and 2!. 4 shipment or storage or immediate consumption, The fowls 21, already slaughtered and dressed, and comprises placing the drawn and dressed are advanced into the .processing room on a suit- 5 fowl in a freezing mold which closes and seals the able conveyor. Into the cavity of each fowl have 6 openings of the cavity of the fowl by means of been placed the cleaned giblets that were rean ice-seal, at the sametime freezing the entire moved when the fowl was drawn, including the fowl. neck which has been severed as close to the 'body A preferred form of apparatus used to carry as possible at 28, after first drawing back the 10 out the invention, is shown in they accompanyouter skin which is allowed to remain integral 10 ing drawing, in which with the body.

The fowls are then expansion refrigerating system or any other suitwrapped in Cellophane or any other suitablema- 65 able refrigerating system, to brine inlets l6 and terial.

By the method described, fowls are killed,

cleaned, dressed and processed, being thus made ready for immediate consumption as soon as defrosted, or for long haul shipments, or for storage. Quick-freezing the fowl while it is still warm arrests and retains more of the natural fi8.VOl.- The fowl is more easily packed by this method as it occupies less space. Its transportation is less costly due to' less Weight. Using this method, the fowl may be killed while in better feeding condition, as it is not necessary to starve or feed thin food for feces-limiting purposes. Where fowl is to remain in sub-freezing storage for long periods of time, this method of preservation avoids the cold storage taint found in birds packed with entrails inside; it also prevents the drying out occasioned in drawn birds packed without ice-seals on the cavity openings.

While I have described one form of apparatus for effecting my method, this has been done by way of illustration only, and other apparatuses may be used as well for the accomplishment of the desired purpose. So, for instance, instead of chambers for the refrigerant around the mold halves, it is obvious that circulating coils may be used for the same intent. I therefore do not wish to limit myself to any particular form of apparatus or to the precise details of the method, as explained herein, butwish to claim broadly the invention as defined in the appended claims.

What I claim as new, is:

l. The method of preserving fowl which comprises drawing and dressing the fowl, placing its giblets in its cavity, and closing cavity openings by submerging portions of the fowl containing openings in water, and freezing the fowl and the water, causing iceseals to form around the openings only.

2. The method of preserving fowl which comprises drawing and dressing the fowl, placing its giblets in its cavity, closing only its cavityopenings by iceseals while freezing the fowl, and dipping the frozen fowl into cold water to form a protective ice film on the outer surface of the fowl.
